How can you tell if your cat is pregnant?
The signs that a cat may be pregnant, including nipple changes, weight gain, appetite and behaviour changes and nesting, how a vet can confirm pregnancy, and how to care for her.

The short answer
Signs a cat may be pregnant include swollen, pinker nipples from around two to three weeks after mating, gradual weight gain and a rounder belly, a bigger appetite, more sleep, and nesting near the end of pregnancy. A vet can confirm it: an ultrasound scan can confirm pregnancy from around three weeks, and an X-ray later in pregnancy can give a more reliable kitten count.
Key considerations
- 01Early signs include swollen, pinker nipples from around two to three weeks after mating.
- 02A vet can confirm pregnancy. An ultrasound scan can confirm it from around three weeks.
- 03Book a vet check to plan her care, and ask your vet what signs of trouble to watch for during birth.
- 04Neutering prevents unplanned litters. A female cat can be spayed after her kittens are weaned.
A pregnant cat needs extra care, and the sooner you know she is expecting, the sooner you can make sure she gets the right food and vet care. Your cat can't tell you she is pregnant, so it helps to know what to look for.
Signs that your cat may be pregnant
Signs can start to show two to three weeks after mating. Some cats show them clearly, while in others they are easy to miss. The most common signs are below.
Nipple changes
This is often the first sign owners notice. The nipples become larger, swollen and pinker. You may also notice the fur around them thinning, ready for feeding kittens.
Weight gain
A pregnant cat gradually puts on weight, and her belly becomes rounder. A swollen belly can have other causes, so if you're not sure she is pregnant, or she seems unwell, see your vet.
Increased appetite
Pregnant cats usually eat more as the kittens grow. Later in pregnancy, she may prefer smaller, more frequent meals. Make sure she always has fresh water, and ask your vet how to feed her during pregnancy.
Changes in behaviour
A pregnant cat may sleep more and be less active than usual. Some become more affectionate and want more attention, while others become more withdrawn or less tolerant of being handled.
Some cats are sick occasionally in early pregnancy. If she vomits often, stops eating or seems unwell, take her to your vet.
Nesting
Towards the end of pregnancy, she will start looking for a quiet, hidden place to give birth, such as a wardrobe or under a bed. She may try to arrange bedding or clothes to make a soft spot for giving birth.
How a vet can confirm pregnancy
The signs above can suggest pregnancy, but they don't confirm it. If you think your cat may be pregnant, take her to a vet.
Your vet may be able to feel the kittens by gently examining her belly, though this isn't always conclusive. An ultrasound scan can confirm pregnancy from around three weeks. An X-ray later in pregnancy can give a more reliable kitten count.
Caring for a pregnant cat
Book a vet check to plan her care, and ask your vet what signs of trouble to watch for during birth.
- Feed her as your vet recommends, and make sure she always has fresh water.
- Give her a clean, warm, quiet place where she can rest and later give birth.
- Don't give her any medicines, flea or worm treatments without checking with your vet first.
- Keep your vet's out-of-hours number handy as her due date approaches, and contact them straight away if you are worried during the birth.
Preventing unplanned litters
Neutering prevents unplanned litters. A female cat can be spayed after her kittens are weaned. Talk to your vet about the right time.
Before you decide
- Has your cat been neutered, and if not, could she have mated?
- Have you booked a vet check to confirm the pregnancy and plan her care?
- Do you know the signs of trouble during birth, and your vet's out-of-hours number?
- Do you have a plan for finding responsible homes for the kittens?
